T0 @ZZ 'whom t may concern Be 1t known that I, FUsA'rAno Irl-ninna subject of the Emperor of Japan, resid- Q ing at San Francisco, inthe county of :San

Francisco and State of California, have invented new and useful Improvementsinl'ce Cream-Delivery Machines', of which iol* lowing is a speciiication. n The present invention relates to improvements in ice cream delivery machines, the object of theinvention being to provide a machine of this `,character in which' ka considerable quantity of ice cream can be contained in a cold condition ready for sale;y and 1n which uniform quantities of ice cream can be easily andexpeditiously discharged therefrom into any desired receptacle such as an edible ice cream cone. t

The' uppery portionV ofV the 1 pusherl rod 33 Ais rounded andy extends ffirst wthrough a wide vopeningl'37 in the* cover `11 Land thenthrough a closely fitting opening inf'kdisk r38 resting `upon saidcov'erf' and closing said wid-efo]; en1ng.v The roundV upper portion ofeachpusher rod 33 isprovided at theto'p with a head39, and between saidv head andthe disk 38 is'co'mp'ressed a kspring fkilcoiled'aroundsaid pusherrod. The retainer rod 36 is secured by a 'removable pin ice 43 indicates an operating handle, extend ing horizontally from the slide piece 44 which slides in a vertically extending slotA the slide piece 44 is a spring 52 coiled around said rod 47, whereby said slide rod is restored to its normal position after it has been depressed by the handle 43. Upon depressing the handle 4,3,` thek linger 48 descends upon the head of the pusher rod 33 and depresses it, compressing the spring 41, so that the pusher rod 33 descends, and since one of n. its notches 32 is in engagement with the upper end of the spring dog 29, the dog 29 also descends, carrying with it the follower 19, andY causing all the icecream in the ice cream tube to descend through a distance corresponding to the distance between the notches 32. The tube container 16 containing the ice cream tube 17 in which is the ice Vcream thus depressed is immediately over a hole formed by a cylindrical wall 54 extending vertically through the shallow water tank 6, so that the ice cream is projected through said hole. rlhe ice cream vender has in the meantime been holding an edible cone indicated at 45, or other receptacle imvmediately beneath said hole, softhat the ice cream thus projected is discharged into said cone.

The ice cream thus discharged is cut off -fiom the Aremainder of the ice cream in the ice cream tube 17 in the following manner.

To the lower end of the slide rod 47 is se- Y Vcured a yoke 56, tothe Vends of which on oppositesides thereof are secured the upper ends .of racks k57, guided by brackets 53 .p secured to the standard 4, which racks 57 Aengage opposite sides of gear wheels 59 loose on a shaft 61, which wheels 5,9 carry .pivoted thereto spring-actuated dogs 62,

which can engage ratchet wheels 63 secured to said sha-ft 61. By this arrangement the ratchet wheels 63 and shaft 61 are rotated byV any vertical movement, either upward or downward,rof the pusher rod 47. rIhe shaft Y 61 is secured at its inner end to an end of a semi-circular cutter 64, of which the other end is secured to a short shaft 66, said shafts 61 and 66 having their bearings in opposite sides of the wall 54 which forms the cylindricalk passage through the water tank 6, through which openingthe ice cream is discharged. c lt thus follows that, after the finger 4S has descended a sufiicient VVdistance tov project -a sufficient quantity of ice cream ,removalof the plunger 19.

through the passage through the water tank, theshaft 61 is rotated, and thus the portion `of'ice cream projected from the tube 17 is severed. from the remainder thereof and is rounded at the top.

`Whenpressure is removed from the handle 43, the rod 47 immediately rises under the action of the spring 52,'thereby removing the pressure from the pusher rod 33 which then rises under the pressure of the spring 41. The follower 19 is prevented from rising with the pusher rodby the engagement of the dog 31 with one of the notches 34 in the iixed retainer rod 36.

When all of the portions of ice cream in.

therefrom, the ice cream tank is rotated e through a suflicient distance to bring the next ice cream tube 17 of the same series into a position in which the head of its pusher rod 33 can be engaged by the finger 48, and the operation heretofore described is then repeated to* discharge the ice cream from said tube in uniform quantities.

YVhen one circular series of ice cream tubes has thus been emptied of' icei cream, the cold water tank is then rotated upon the table, by a handle 50 through a sui'liifient angle to bring a second pair of gear wheels 59 into the same position as the first pair of gear wheels 59, so that they can be engaged by said racks 57,v in the saine manner as before. It is for the purpose of permitting this substitution to take place, and the gear wheels 59 tobe moved out of the way when not required, that the extensions 5 are provided. rEhe shaft 61` rotated by said gear wheels 59 is of different length from the sha-ft 61, since the circular series of ice cream tubes now to be discharged lof ice cream are at a different distance from the center of the tank 9 from that of the series already emptied. The finger 48 is stifliciently longY to engage either the heads 39 ofthe first series or the heads 39 of the second series.

rlhe operation of discharging the ice Y cream is now repeated'upon the second series of tubes. Y f

When the tubes of 100th series are empty, the disks 3S are withdrawn from the pusher rods 33, this being rendered possible by said disks having slots G5 of width not less than said rods 33 extending from the center to the circumference of the cover; 11V is then raised. that the retainer rods 36 can'be removed. This allows the followers 19,v carrying the spring dogs 29, 31, to be raised ventirely out of the tubes 17, and then said tubes ,can be removed from the tube containers'l. The projection at the lower end of the rod 36 engaging the extension 21 makes possible the The space in the tank 9between the ice The pins 42 are then withdrawn, so'

cream tube containers I6 is filled With' insulating medium), and escapesthrough ay stationary pipe 69 connected with a side ot said cold Water tank 6, and preferablyeii-v` tending iirst upward and then downward to 'toi'm a Water seal to prevent any air be-` p ing admitted into said tank Whichfvvould raise its temperature. Said pipe- 69 is conducts the escaping. Water to 'any rsuitable receptacle.

It should'be noted that, when the followerL is placed in position, the air therein is trapped and, when the follower is depressed, 'forms a cushion preventing `actual contact oie the central portion of the Jfollower With the ice cream. f
